Definitions

  • the present invention relates generally to conferencing services and similar group communication services. More particularly, the present invention relates to the establishing of conferences that have been previously scheduled or conferences that meet certain criteria.
  • the Session Initiation Protocol is an application-layer control protocol for creating, modifying, and terminating sessions with one or more participants. These sessions may include Internet telephone calls, multimedia distribution, and conferences including voice, video and messaging conferences.
  • SIP Session Initiation Protocol
  • OMA Open Mobile Alliance
  • XDM XML Document Management
  • conferencing service is a scheduled conference.
  • group definitions that are stored within the network include information about the date and time at which the conference will be initiated by the conference server.
  • the conference server initiates the conference by inviting conference members (as defined in the group/conference definitions) to join the conference.
  • Conferences can also be scheduled using other systems.
  • One such system is the iCalendar system over SIP.
  • iCalendar specifies a calendar object presentation format that is used to provide and deploy interoperable calendaring and scheduling services. iCalendar is discussed in detail in the Internet Engineering Task Force (IETF) Request for Comments No.
  • conference participants can be notified about the scheduled event. This notification can be provided in several manners. For example, one method of notifying participants involves sending an iCalendar- fo ⁇ natted calendar request to each participant. Other types of corresponding requests may also be sent. When sending these requests, either the SIP protocol, the XCAP protocol, or a protocol of another type may be used.
  • an iCalendar-formatted calendar event will contain a date and time for the scheduled conference, the subject of the conference, a participant list, and other information about the conference. Additionally, an iCalendar-formatted calendar event may also include a unique identifier (UID) that is used to uniquely identify the event.
  • the conference server for example a push-to-talk-over-cellular (PoC) server, is triggered in order to establish the conference, and the conference server invites participants to join the conference.
  • the actual invitation can take the form of a SEP INVITE message which contains the uniform resource identifier (URI) of the conference (i.e., the Group URI).
  • URI uniform resource identifier
  • the Group URI is used by the invited participant to identify that the invitation emanated from a certain pre-defined group.
  • the procedure described above is applicable for both scheduled conferences and other pre-defined conferences that are triggered when certain circumstances are met.
  • a procedure can be used for predefined conferences which are set to be established when a certain number of conference participants are registered to the network.
  • a conference server evaluates the criteria and, when the criteria is met, the conference is established.
  • the information provided by conference server invitations is helpful to a recipient, there is additional information that would be helpful that is not made available by the conference server.
  • outgoing conference indications include a unique identifier that indicates to a recipient that the conference invitation is being sent due to the occurrence of a certain event, such as a previously-scheduled calendar appointment or certain criteria (such as when a certain number of conference participants are registered to the network) are met.
  • a certain event such as a previously-scheduled calendar appointment or certain criteria (such as when a certain number of conference participants are registered to the network) are met.
  • an invited conference participant is capable of identifying that a conference invitation is related specifically to a previously sent scheduled calendar event or other types of pre-defined conditions.
  • the payload of the conference invitation is not unnecessarily increased, as only the unique identifier value is sent to the user.
  • the various embodiments of the present invention maybe implemented on systems regardless of how the scheduled conference is initially created.
  • Various embodiments of the present invention can be applied to a variety of conference types, including but not limited to, scheduled conferences.
  • certain embodiments of the present invention can be applied to situations where a client creates a conference event that is established when certain conditions are fulfilled, for example based upon the availability and/or location of the participants.
  • Figure 1 is a diagram showing an implementation of the present invention when using a SIP mechanism
  • FIG. 2 is a diagram showing an implementation of the present invention when using a XDM
  • Figure 3 is a perspective view of an electronic device that can be used in conjunction with the implementation of various embodiments of the present invention.
  • Figure 4 is a schematic representation of the circuitry which may be included in the electronic device of Figure 3.
  • outgoing conference indications include a unique identifier that indicates to a recipient that the conference invitation is being sent due to the occurrence of a scheduled or other conditionally established event,
  • iCalendar is used to describe calendar events.
  • iCalendar specifies the UID property as a unique calendar identifier in the following manner:
  • This property defines the persistent, globally unique identifier for the calendar component.
  • the iCalendar event can be sent, for example, as part of a Group Advertisement (using the OMA PoC and OMA instant messaging (IM) feature), via calendar synchronizations, etc.
  • the server may only be sent a link to the calendar information.
  • a SIP INVITE message is sent to the intended participants.
  • SIP UPDATE SIP UPDATE
  • SIP REFER messages SIP UPDATE
  • SIP INVITE message contains the iCalendar UID, another type of unique identifier, or a link to detailed information (e.g., a link to calendar information) in a Call-Info header field as follows:
  • the client device can use the UID value contained in the Call-Info field to associate the invitation with the scheduled event or other conditionally established event.
  • the IETF's Request for Comments 3261 (which can be found at "www.ietf.org/rfc/rfc3261.txt” and is incorporated herein by reference) specifies "icon”, "info” and "card” values for the "Purpose” parameter of the Call-Info header.
  • the "info" value is used when the Call-Info header indicates that the conference invitation is being sent due to the occurrence of a scheduled event.
  • an entirely new purpose value may be used other than those discussed above.
  • a SIP header other than the Call-Info header in order to carry the conference event identification.
  • a number of options exist for transporting the identifier for the outgoing conference invitation A first option involves the use of iCalendar.
  • the IETF 1 S Request for Comments 2445 (which can be found at "www.ietf.org/rfc/rfc2445.txt" and is incorporated herein by reference)inchides its own Multipurpose Internet Mail Extensions (MIME) type "text/calendar” for iCalendar events.
  • MIME Multipurpose Internet Mail Extensions
  • an iCalendar- formatted document can be included into an INVITE request as an additional payload.
  • a second option for transporting the identifier involves the use of a Globally Routable User Agent URI (GRUU).

  • the IETF draft "draft-ietf-sip-gruu-1 l.txt" (which can be found at www.ietf.org/internet-drafts/draft-ietf-sip-gruu-l l.txt and is incorporated herein by reference) specifies the GRUU as a globally unique SIP UA identifier.
  • the GRUU is formed from the URI by adding a unique "gr" attribute in the end of the URI.
  • the GRUU can be used to uniquely identify different instances of the group.
  • One such instance of the group can be a conference event that is established when certain conditions are met (e.g., date and time, availability of the participants, etc.).
  • an XDMS server needs to allocate a GRUU for the newly created conference instance.
  • the GRUU can be obtained by generating it locally or by requesting it as part of a REGISTER procedure. In this particular case, XDMS generates the public GRUU locally.
  • sip:golf-team@example.com;gr kjh29x97us97d
  • the GRUU is sent to the participants of the scheduled conference event, for example as part of a Group Advertisement request or in an iCalendar calendar event.
  • the conference server includes the GRUU in the Contact header or other appropriate header (e.g., From, P-Asserted-ID or a header where Service-identity type of information is placed in the future) of an outgoing INVITE request in the following form:
  • FIG. 1 is a diagram showing an implementation of the present invention when using a SIP mechanism.
  • a client device referred to herein as a creating device 100
  • a creating device 100 is capable of creating a scheduled conference or other conditionally established event by communicating with a conference server 110 at 105.
  • the communication from the creating device 100 to the conference server 1 10 can occur, for example, using i Calendar over SIP.
  • the conference server 110 sends a notification about the scheduled conference at 115 to other client devices 120 whom the creating device has requested should be invited to the scheduled conference.
  • the conference server 110 proceeds to evaluate the pre-defined conditions for establishing an conference, e.g., whether the conditions for the conference has been reached. Once the conditions for conference establishment have been reached, the conference server 110 proceeds to send a conference invitation at 135 to the creating device 100 and to the other client devices 120.
  • the conference invitation can be included in a SIP message (e.g., SIP INVITE, SIP UPDATE or SIP REFER messages) with the information pertaining to the conference event, (e.g., in the form of an iCalendar UID, iCalendar payload or GRUU).
